Southern California rap artist Guerrilla Black and five other South Bay residents were arrested Wednesday, suspected of operating two major fake credit card manufacturing businesses that took in more than $40,000 a month, Manhattan Beach police said.

The rapper, Charles Tony Williamson, 35, of Torrance, who previously was indicted on similar charges in Seattle, and the others allegedly victimized banks and credit companies in the United States, including American Express, Capital One, Chase, Citibank, Bank of America and Kinecta, Manhattan Beach police Officer Stephanie Martin said.

In July, federal authorities accused Williamson of buying used credit card information stolen by a Netherlands man and a Maryland man. Authorities allege Williamson stole more than 27,000 credit card numbers and defrauded banks of more than $150,000.

Williamson is a West Coast hip-hop rapper from Compton whose debut album, "Guerrilla City," came out in 2004. His brother is rapper Hot Dollar.
